A study of skin characteristics with long‐term sleep restriction in Korean women in their 40s

Abstract

Background Previous studies have demonstrated increased pore size and darkening skin color with total sleep deprivation. There are many studies of skin characteristics with short‐term sleep restriction, but there are few studies on skin characteristics when sleep is restricted more than three consecutive days. This study evaluated skin changes with sleep limited to 4 hours per night for six nights. Materials and Methods The study included 32 Korean women in their 40s. Skin hydration, desquamation, barrier recovery, texture, gloss, transparency, elasticity, crow's feet, frown lines, and color were measured. Individual sleep time was monitored by smartwatches. Subjects slept 8 hours per night for six nights in week one and 4 hours per night for six nights in week two. Results Skin hydration was significantly reduced after 1 day of sleep deprivation, and it continued to decrease. Skin gloss, desquamation, transparency, elasticity, and wrinkles were significantly aggravated after 1 day of sleep deprivation. Skin texture was significantly aggravated on the fourth day of sleep restriction. Elasticity was most affected by reduced sleep, with a standardized coefficient of −.320, indicating a significant decrease over time as compared to other characteristics. Conclusion Skin hydration was gradually decreased with sleep restriction. Skin texture did not change after only 1 day of sleep restriction. It is a new finding that elasticity decreases more than other skin characteristics with prolonged sleep restriction.

Evaluation of changes in skin characteristics due to the poor quality of sleep caused by smartphone usage

“…Significant age-related changes, including reduced elasticity and increased wrinkles, have been reported. 4 However, other studies have shown that aging accelerates in groups with high PSQI scores. Thus, chronically inadequate and poor quality sleep accelerates intrinsic aging, and poor sleepers are more dissatisfied with their physical appearance than good sleepers.…”

“…3 In addition, studies have shown that reduction of sleep from 8 to 4 h, even for 6 days, reduces elasticity and leads to skin aging. 4…”

Impact of Exposome Factors on Epidermal Barrier Function in Patients with Obstructive Sleep Apnea Syndrome

“…Sleep restriction during one night increased TEWL and decreased hydration and elasticity in 24 healthy females [ 30 ]. Moreover, sleep deprivation to 4 h per night increased TEWL and desquamation, and decreased SCH and elasticity in 32 healthy women [ 31 ]. External factors related to poor sleep quality, such as smartphone usage, also impair skin by decreasing hydration and elasticity [ 32 ].…”

“…Our study also observed that patients with a more severe OSAS disease could have greater skin impairment, reflected in higher TEWL values. This may be explained because severe OSAS patients have a long disease duration with poor sleep quality [ 14 ] and it has been previously observed that longer sleep deprivation is also associated with higher TEWL values [ 31 , 32 ].…”

Identification of skin aging biomarkers correlated with the biomechanical properties

“…In this study, R2 was used as the gross skin elasticity. 9,29 Ultrascan UC22 (Courage and Khazaka Electronics Ltd.) is an instrument used for ultrasound imaging of the skin, particularly skin layers at a penetration depth of 6-8 mm, using a 22 MHz probe. The measurement is based on the ultrasound waves being reflected differently according to the structures and properties of different tissues in the skin.…”
